On generalized Mazhar-Totik operators

Wachnicki E.

Demonstratio Mathematica

2005

Vol. 38, nr 1

143--151

In this paper we consider the continuous version of the operator investigated by Mazhar and Totik ([2]). Some applications for the limit problem are indicated.

Global approximation theorems for the generalized modified Szasz-Mirakyan operators in polynomial weight spaces

Świderski T.

Demonstratio Mathematica

2003

Vol. 36, nr 2

383--392

In the present paper we study the modified Szasz-Mirakyan operators. This modification generalizes the integral operators proposed by S. M. Mazhar and V. Totik in [3]. Moreover we present bonduary value problems related to these integrals.

The martingale decomposition and approximation theorems for a generalized random permanent function

Rempała G.

Demonstratio Mathematica

2001

Vol. 34, nr 2

431-446

The paper presents some recent developments in the theory ofpermanents for random matrices of independent columns. In particular, it is shown that the theory in a natural way incorporates and extends that of U-statistics of iid real random variables. An extension of the famous martingale decomposition (or H-decomposition) for U-statistics to a certain class of matrix functionals, which includes in particular a classical permanent function, is given.

On conditional Jensen equation

Ziółkowski M.

Demonstratio Mathematica

2001

Vol. 34, nr 4

810-818

On approximation of (1.A) semigroups by discrete semigroups

Bobrowski A.

Bulletin of the Polish Academy of Sciences. Mathematics

1998

Vol. 46, no 2

141-154

A generalization of a recent result of N. Tanaka concerning approximation by "integrated" discrete semigroups is presented.
